LIQUID-TREATING INSTRUMENT.

'- Application filed September 9, 1921. Serial No. 499,545.

T 0 all whom it may concern:

Be it known that I, FORD E. BEIDLER, a citizen of the United States ofAmerica, residing at New York city, New York County, N. Y., haveinvented a new and useful LiquidTreating Instrument, of which the following is a specification.

Mly invention relates to devices for treating iquids electrically forvarious purposes, such for instance, as purifying or softening water andbleaching or removing impurities or undesirable substances from otherliquids.

The main object is to provide a simple, inexpensive device which may bereadily used by anyone for quickly treating liquids at a minimum ofexpense.

Fig. 1 is a perspective view showing a device embodying the improvementsof my invention in use.

Fig. 2 is a side view and partial longitudinal sectional view of adevice embodying the improvements of my invention.

Fig. 3 is a transverse sectional view of the same.

Fig. 4 is a transverse sectional view of a modification.

The device has two electrodes 3 and 4. These electrodes are preferablyformed of an alloy whose principal component is aluminum. I alsopreferably add to the aluminum certain small proportions of other metalsfor the purpose of accelerating the action and prolonging the life ofthe electrodes without deleteriously affecting the liquid which is to betreated. As one example of the specifications for these electrodes Iwould mention a composition of aluminum containing approximately twopercent of magnesium and less than one half of one percent of iron. Asmall percentage such as one half of one percent or less of silicon mayalso be used to advantage. Preferably the alloy contains ninety-seven ormore percent of aluminum.

To facilitate the use of the device, I preferably provide a handle 5 towhich the electrodes are secured, and which may have a central passagefor the wires or conducting cord 6. For convenience in use I also preferto provide a suitable form of attachment plug 7, which may be used inconnection with any ordinary socket or receptacle. The outer ends of theelectrodes may also be relatively positioned by means of an insulatingpiece 8, so as to prevent the two electrodes from coming in contact. I.also prefer to provide an outer guard, such as a per forated tube 9,surrounding one or both of the electrodes. During treatment heat "andgas are generated and the perforated tube substantially assists theaction by causing circulation of the liquid being treated.

Fi 2 represents the device in full size as suita le for use in smalljars or other receptacles, aS illustrated in Fig. 1. The instrument issimply inserted in the 'ar or receptacle and current turned on. hedevice as illustrated is intended for use on a 110 volt circuit. Whenthe current is turned on, the electrolizing action causes a circulationof the liquid adjacent the electrodes, and the impurities and otherforeign matter are very rapidly removed. The action is greatlyaccelerated by stirring the liquid. The impurities some times rise tothe surface of the liquid, and other impurities fall to the bottom. Ineither case they may be readily removed by filtration.

I found that the device will quickly remove the alkalies and certainmineral salts and most colors from water or other liquids, and will alsopurify water containing other undesirable substances. It will alsobleach other liquids. It is also possible to remove the dark color fromiodine solutions so that the iodine will not produce the stain which isconsidered characteristic but undesirable. The device may also be usedto remove impurities from liquors and produce the effect ordinarilyproduced by time, although without increasing the alcoholic content.

The electrode 3 and 4 may be concentric as shown in Fig. 4, in whichcase the outertube 4' acts as a guard to the inner electrod 3. The innerone may be solid and in some cases may be of carbon or other suitablematerial.

I claim:

1. A device of the character described having two electrodes, one ofwhich at least is composed of aluminum and less than three per cent ofmagnesium.

2. A device of the character described having two electrodes, one ofwhich is composed of approximately ninety-seven per cent of aluminum,less than half of one per cent of iron, approximately half of one percent of silicon and approximately two per cent of magnesium.

3. A device of the character described having two electrodes, one ofwhich is composed of an alloy containing more than ninety-five per centof aluminum, a trace of iron and silicon and less than three per cent ofmagnesium.

4. A device of the character described having two electrodes, one ofwhich is composed principally of aluminum alloyed with less than threeper cent of magnesium and a small percentage of iron.

5. A device of the character described having two electrodes one ofwhich is composed of more than ninety-five per cent of alu- 15 minum,less than three per cent of magnesium and less than one half of one percent of silicon.

6. A device of the character described having two electrodes one ofwhich at least is composed of approximately ninety-seven per cent ofaluminum, approximately two per cent of magnesium and approximately oneper cent of iron and silicon.

7. A device of the character described. having two electrodes one ofwhich at least is composed principally of aluminum with less than threeper cent of magnesium and approximately one half of one per cent ofanother element such as iron.
